This is the GN ‘fire training car’ - It survived the BN merger and was repainted in Cascade Green with the same flames - a neat looking car. I suspect it was scrapped years ago.
I believe it’s pictured in “Great Northern Color Guide to Freight and Passenger Equipment”
by David H. Hickcox - Morning Sun Books, Inc., 1995. May be in some other books too.
Great Northern Ry. Historical Society might be able to help with more information too.
I have a photo of it in it’s BN green paint, but it is in slide format, and none of my slides have been transfered to other media. Maybe it’s time to get on it. The slides are more than 25 years old. I hope they held up.
